Most of these as I hope you're seeing from the other responses are just examples of "the false dilemma". What is sad is that Kent Hovind has had that pointed out to him many, many times, yet he continues to preach the same false dilemmas just as though they were valid. It might be just ignorance until the errors are pointed out to him, but when he continues using them it starts to look more and more like he is just a liar.
For example.
How did the gecko develop its outstanding ability to climb? Were the hairs on its toes useless up until the time they were just right? Why haven't a host of other lizards developed such a beneficial ability?
Any one that has seen chameleons run up and down walls, trees, bushes, table legs and drainspouts knows that the Gecko is not unique. Lots of lizards climb.
How did the giraffe slowly develop such a brain structure that would allow it to raise and lower its head without any problems? If they are the result of millions of years of evolution, wherein they grew longer and longer necks overtime in order to eat from the trees, why aren't there hundreds of other animals with such necks?
The Giraffe got it's brain and plumbing system just like it got its neck, in little steps and over a long period of time. And the giraffe is NOT the only such critter. There have been many such long necked critters. Ever see a picture of Brachiosaurus?
What Kent Hovond tries to do is toss something out and claim it's a problem, then move on before the audience laugh reflex sets in.
